To all whom it may cavern:

Be it known that I, HARRY A. SnLLnRs, a

citizen of the United States, and resident of th Roxbury, county of Suifolk, State of Massachusetts, have invented an Im rovement in Nursing Nipples, of which the ollowing description, in connection with the accompanying drawing, is a specification, hke characters on the drawing representing like parts.

This invention relates to nursing nipples and it has for its general object to provide a nursing nipple which will not collapse while bein used and Which is non-leakable, so that it t he nursing bottle with the nipple thereon is laid down on its side without being use the contents of the bottle will not leak out through the nipple.

, In order to give an understanding of my invention l have illustrated in the drawin s a selected embodiment thereof, which wil now be described after which the novel features will be pointed out in the appended claims.

Fig. 1 is a vertical sectional View through a nursing bottle having my improved nipple ap lied thereto. M

ig. 2 is a section on the line 2-2, Fig. l. Fi 3 is a sectional view through the nippTe removed from the bottle and taken on the line 3-3, Fig. 2.

.1 indicates the nursing bottle which may have any suitable or usual construction and which is provided at its upper end with the bead 2, to which the nipple is attached, all as usual. My improved nipple is indicaved at 3 and it is formed with the enlarged end i which is adapted to be placed over .the bead 2 of the bottle as usual.

In order to provide a non-leaking nipple,

T construct my improved nipple with a valve which is arranged to normally close the o ening 5 in the neck of the bottle, but

wlaich will open automatically to allow the milk to be taken from the bottle whenever the nipple is used. This valve is shown at a stem 7 which is secured to the wall of the nipple at the enlarged portion 4, so that e valve is permanently attached to the nipple. The stem 7 can be secured to the nipple either by cementing it thereto or in any other suitable way. The construction is such that when the nipple is placed on the bottle, as shown in Fig. 1, the valve 6 will lie against the top of the bottle neck and thus act as a valve to close the neck of the bottle. The resiliency of the valve 6, however, permits it to open awa from the bottleneck as shown in dotte lines, Fig. 1 whenever a suction is created in the nipple. Therefore Whenever the nursing nipple is being used the milk or other contents of the bottle can flow freely through the neck 5 into the nipple, but as soon as the suction on the nipple ceases, then the valve automatically closes the bottle neck. With this construction it is possible to lay the bottle down on its side without danger that the contents thereof will leak out through the nipple.

The stem 7 not only provides means for.

from the bottle by the stem 7 at the point where the stem is attached to the nipple and this provides an air vent 8, on each side of the stem 7 through which air is admitted to the nipple. This makes the nipple non-collapsible one.

' I claim:

1. The combination with a bottle, of a nipple attached thereto, and a valve secured to the nip le and normally resting against the end oi the bottle neck thereby to close the same, said valve being movable bodily away from the end of said neck when suction is produced in the nipple.

2. The combination with a bottle, of a nipple applied thereto, a valve having a hinged connection to one side of the nipple and adapted to close the neck of the bottle.

3. Tn a nursing nipple, the combination with a nipple body adapted to be applied to the neck of a bottle, of a flap valve of resilient material having a hinged connection with one side of the nipple, and adapted to close the neck of the bottle when the head at the neck of the bottle, said. valve nipple is applied to the bottle. normally closing the nevk of the bottle and.

4:. The combination with a, bottle of a the stem holding the nipple separated from 10 nipple applied to the nevk thereof, a flap the bottle sniliciently to form an air vent. 5 valve of resilient material having a stem In testimony whereof, I have signed my which is secured to the inner wall 01" that name to this specification.

portion of the nipple ,which embraces the HARRY ANDREW SELLERS.
